There are a lot of things that we might think we need in our lives, but the reality is they are really wants. We need air, water, food, and coffee (ok not coffee) but the others are true. Our bodies need air, water, and food to survive. Everything else are nice to haves. The world tells us that we need things. There are flashy things, fast things, big things, things that will help us get more, and things that will give us power and prestige. Many of these things are either wants or things that will trap us and have nothing to do with our real needs in this life. If you spend time studying the Bible you are going to find some common themes.
You will see that there are some things that you really do need, and they are not what the advertisements tells us we need. They are not things you can touch or feel, but they are true needs.
